IMPROVEMENT Nomisma-Names Speeifieation'forming part of Letters Patent No. 39,776,'dated September 1, 1863.

To all/whom 'it may concern: 4

Be it known that I, .WILLIAM K. PLATT, a

. resident of the city and county of PhiladeL, phia, and` State of Pennsy`1vania, have invent ed a new and useful Improvement in the Garding-Engine; and I do hereby declare the same to be fulldescribed in the following specification 'and represented in the accompanying drawings, of which` Egure 1 is a top view, Fig. 2 a vertical secj tibn, and"Fig, 3' a front view, of the 'rubbers' or condensing-rollers of a i'inisher carding-engine, together with my invention. v

In such drawings I have not deemed itneces- -sary to show the remaining parts/of a finisher earding-engine, because they' are well-known to persons skilled in. the art of carding/wool or other iibrous material.

In carrying `out my invention I combine with a- 'cardng-engine a mechanical means,

device,.or devices by which the electricity which l may gather in the wool or brous material tricity I combine. wit-l1 the' carding-engine an' v attraction bar or device and one or more electrical conductors, the combination of such with thecardi'ngengine constituting the nature of my invention. The said-attraction-bar, being of metal and formed somewhat like a sawblade, may be arranged or placed directly in front of or near to the rubbers of a finisher card, and so as to be directly underneath and give support to the series of ropings or slivers proceeding therefrom, and this attraction bar or device should have an electric connection with the door on which the machine may be situated, or with the ground under the same.

In the drawings, wb c denote the condensf ing-rubbers of a finisher carding-engine, while l d is the attraction-bar, and e the electrical conductor leading therefrom. The attaction-bar is represented as provided on its upper edge with a series ofl semicircnlar notches to receive the slivers or ropin gs as they proceed from the rubbers. In passingover and in contact with the said bar the slivers or ropings will have their surplus electricity abstracted from their; by it, such electricity being conveyed away to the earth through the conductor.

A metallic vbar and an electrical conductor may be applied to any other description of carding-engine-as, for instance, to the first or second breakers, or to a inisher provided with tubes for twisting the slivers, and so that the bar, by being in contact with or' close proximity with the cardings or slivers that may be made by such engine, shall operate to remove from such cardng or sliversl the accumulated elec-v tricity thereof. l

I claimv 'A The combination of the electrical attractionbar and its conductor, cr the equivalent or equivalents thereof, with a eenling-engine,- the same being substantially'as and for the 'purpose specified.-
